77.    (30553-!-item-!-188;#058&005527)

Citizens of Parktown are worried by the increased frequency of serious crimes committed by local teenagers.  In response, the city government has instituted a series of measures designed to keep teenagers at home in the late evening.  Even if the measures succeed in keeping teenagers at home, however, they are unlikely to affect the problem that concerns citizens, since most crimes committed by local teenagers take place between 3 p.m. and 6 p.m.
Which of the following, if true, most substantially weakens the argument?
A. Similar measures adopted in other places have failed to reduce the number of teenagers on the streets in the late evening.
B. The crimes committed by teenagers in the afternoon are mostly small thefts and inconsequential vandalism.
C. Teenagers are much less likely to commit serious crimes when they are at home than when they are not at home.
D. Any decrease in the need for police patrols in the late evening would not mean that there could be more intensive patrolling in the afternoon.
E. The schools in Parktown have introduced a number of after-school programs that will be available to teenagers until 6 p.m. on weekday afternoons.

答案为什么是B啊？我觉得D很对的。。。

argument是说，因为青少年犯案大多都是下午3-6点，所以在晚上把青少年关在家里不能解决其增长的恶性犯罪 ...

同意！

我能问下E为什么错吗？
我的理解是，虽然有这个项目，但是执行的效果好不好不知道，因此不能作为削弱的理 ...

argument是说，因为青少年犯案大多都是下午3-6点，所以在晚上把青少年关在家里不能解决其增长的恶性犯罪率。
选项B是说3-6点犯的一般都是小案，构不成恶性，所以正确。
选项E说学校已经在下午6点前有活动，这有可能会导致下午犯案率下降，但无法削弱“大多犯案都在下午，所以晚上把他们关在家里能降低恶性犯罪率。”

泾渭不凡

题目问是是削弱。

就是以下哪个选项可以支持“政府限制青少年夜晚出行游荡可以减少青少年犯重罪”。

D是说政府限制令无效的啊~（D选项明显和政府的提案相关度不如B密切）

Crimes commited in the afternoon are not SERIOUS crimes.
